When we are given the reactants of a chemical reaction, the first task is to find out if any reaction occurs, and if so, what products are formed. Then, we may proceed to write out the chemical equation, placing the symbols of the reactants on the left-ha...
Express your answer as a chemical equation. Identify all of the phases in your answer. Balance the following equation and indicate whether it is a combustion, combination or decomposition reaction: NH_4NO_{3(s)} \to N_2O_{(g)} + H_2O_{(l)}. ...
Write a balanced equation for the combination reaction described, using the smallest possible integer coefficients. When zinc oxide combines with water, zinc hydroxide is formed. Write the balanced chemical equation for the reaction between zinc c...
balance the equation to show that the Law of Conservation of Mass is observed during the reaction. In our example you can see that the two atoms of hydrogen and the two atoms of chlorine in the chemical units of the products must have come from two chemical units of the reactant, hydroch...
The product of a chemical reaction has completely different chemical properties than the reactants. However, the physical properties of the product may or not be the same as the reactants. Products are represented on the right-hand side of a chemical equation....

3MnO(2)(s) + 4Al(s) overset("heat")rarr 2Al(2)O(3)(s) + 3Mn(s) No chemical reaction occurs because manganese is less reactive than aluminium.
balance the equation to show that the Law of Conservation of Mass is observed during the reaction. In our example you can see that the two atoms of hydrogen and the two atoms of chlorine in the chemical units of the products must have come from two chemical units of the reactant, hydroch...
The extracted, individual reaction rates allowed the derivation of design rules for FEBIC parameters towards highest conversion efficiencies and highest lateral resolution. Polysaccharides are a large class of biopolymers which exhibit a large structural and chemical diversity and, con- sequently, a ...
